In July 1649, Margaret Mairtine, a resident of the burgh of Inverkeithing in Fife, appeared before the authorities to answer charges of witchcraft, including allegations of attending witches' meetings. Her case was deeply entwined with the historical shadow of Beatrix Thomsone, who had been executed for witchcraft two decades earlier in 1629. In her confession, recorded on 9 January 1649, Margaret identified Thomsone as the individual who had originally brought her to the Devil, establishing a generational link in the local narratives of maleficium that preoccupied the community at the time.
The reach of Margaret’s testimony extended far beyond her own culpability, as she became a pivotal figure in a wider series of legal proceedings. In the months surrounding her trial, she denounced a vast network of twenty-two individuals, including Bessie Wilson, Marjorie Fergie, Joannet Smetoune, and John Greve, among many others. These denunciations suggest that Margaret functioned as a key informant within the judicial machinery of seventeenth-century Fife. By linking her own history to the memory of an executed woman and casting suspicion upon a broad circle of her contemporaries, Margaret’s confession became a foundational element in the prosecution of those she named.
